Subject: [PATCH] Make configure test for LD_NO_UNDEFINED_FLAG on Solaris work 
w/autoconf 2.69
Date: Fri, 15 May 2015 21:27:26 -0700
From: Alan Coopersmith <alan.coopersmith at oracle.com>
To: xorg-devel at lists.x.org

After upgrading from autoconf 2.68 to 2.69, this test started failing with
"conftest.c", line 149: undefined symbol: NULL
so use a raw 0 pointer to avoid header dependencies in the autoconf
generated test case.
